Batman’s Batsuits from The ‘Dark Knight Rises’ and ‘Batman Begins’ are expected to achieve between £40-60k and £30-40k respectively, Keira Knightley’s ‘Love Actually’ wedding dress is expected to achieve £5-7k and Michael Ironside’s ‘Jester’ flight suit from ‘Top Gun’ is expected to fetch between £6-8k at the auction. Film fans will have an opportunity to see all these original items on display in the two weeks ahead of the auction at the preview exhibition.

Hey you guys! The sloth stunt mask from 80s favourite 'the Goonies' is also up for grabs.

This will coincide with a number of special screenings at the BFI IMAX, including classics such as ‘Gladiator’, ‘Top Gun’ and the Christopher Nolan-directed ‘The Dark Knight’ trilogy. What’s more, film fans who pre-book their tickets for the screenings will have a chance of winning some exclusive movie artefacts, including Barbarian’s sword and scabbard from ‘Gladiator’ as well as a Gotham Rogues t-shirt and a Batcave hanging bat from ‘The Dark Knight’ trilogy.

Stephen Lane, Prop Store CEO, said: “We’re thrilled to announce our third live auction in London and are excited to be partnering with ODEON again. This year brings an opportunity for film fans and collectors alike to view some of the world’s most iconic film and TV items for free, and bid to secure their own pieces of movie and television history. A truly unique event for a global audience.”

Andy Edge, commercial director at ODEON UK & Ireland added: “We’re incredibly proud to help Prop Store bring these iconic film mementos to the public, and give UK film fans a chance to walk away with their own piece of cinema gold.”

“As Europe’s leading cinema chain, we’ve enjoyed bringing many of these blockbusters to the big screen throughout the years – and we can’t wait to welcome the iconic props through our doors this September.”

– The Prop Store auction is suitable for fans with a variety of budgets. Some of the least expensive lots in the auction include crew t-shirts and caps from the ‘Star Wars’ franchise estimated at £60–£80, and a selection of production-used scripts and posters from the film ‘Labyrinth’ starring David Bowie, estimated to sell for an affordable £200.
